Requirements

• I have updated Mushroom to the latest available version
• I did a search to see if there is a similar issue or if a pull request is open.

Is your feature request related to a problem?

Would be great to have a calendar card as the existing template card does not allow multiline secondary info
Ideally the card should display the event(s) name(s) followed by the event date and start time and possibly the location of the event
Last but not least having the location clickable to open it on Google Maps would be great
